Can we make it that to post you first have to post in the introduce yourself forum, if it is a Machine this may foil them.Also on facebook everyone has to be approved. On other forums you have to put in a code do we have any of these measures or can they be easily installed?

I am unsure if i have done the right thing but have deleted 3 pages of spammer logins and activated the anti bot question - I hope, this can be turned off again, but may stop this infestation if it is a machine.
